, Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-pane, double sided, 2-40 layer multilayer professional providers, to provide customers with high-precision, Shenzhen circuit board quality, quality assurance, reasonable prices. From a design standpoint buried vias board power planes, a through-hole is mainly composed of two parts, one in the middle of drilling (drill hole), and second, the drilling pad area surrounding the circuit board wiring buried vias principle, determines the size of small vias. Obviously, high-speed, high-density PCB design, designers always want vias as small as possible, so that the board can leave more wiring space, in addition, smaller vias, its own parasitic capacitance The smaller, more suitable for high-speed circuits. Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 layer multilayer circuit board professional supplier, to provide customers with high-precision high quality Shenzhen board, quality assurance, reasonable prices. Also known as the through-hole vias multilayer circuit board buried vias, from top to bottom all get buried blind hole circuit boards, in the four PCB vias throughout layer, a layer of irrelevant trace will interfere. Vias are divided into two types: 1, PTH hole PTH (Plating Through Hole), hole wall copper, usually over current hole (VIA PAD) and member aperture (DIP PA). 2. Non-PTH NPTH (Non Plating Through Hole), no copper hole wall, usually positioning holes and screw holes. Buried vias board costs, Guangdong buried vias boards, Newell record (view) provided by the Department of Shenzhen-Electronic Technology Co., Ltd. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) is a professional "pcb board" company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "division Snyder, Newell a" brand has a good reputation.
